Always great. System is over 10 years old and resin needed to be replaced. Had to take tank to the shop...quickly repaired tank and returned to service. Called ahead and on time.
The process was easy to have the system installed to provide us with safer water.
Thanks to you folks at Culligan for providing good and reliable service at a reasonable price. You are responsive to my delivery needs, which makes our doing business together very convenient...a big plus. Keep up the good work.

Nice people and nice company
Cost and convenience. Renting my unit is very affordable and the added bonus that you provide the salt and come put it in is priceless
Purchased my RO system from them and have had it for 18 yrs. The personnel are always courteous and helpful. They know their products even if it is old. They never tried to upsell me anything. My system is working great after a service call. My only knock is the price of the filter. I would not trade the system and service that I received from them and the system. Great tasting water after all these years. I highly recommend Culligan of New Braunfels.
Fast and flexible scheduling, professional installation, and high quality products. Sales rep explained all parts of my whole-house water softener, filter system, and the RO system. He came up with the best-priced bid under 6 other competitors. Professional installers completed the job quickly and explained every part of the installation.
OUTSTANDING customer service with friendly and professional install! The 3-years of follow-on service has been truly impressive! The Seguin Culligan Team know their business & how to treat their customers! Highly recommend to anyone looking for service! This team ROCKS!
I was asked to comment on Culligan's products and services. Products: the way it makes my water feel when I take a shower, and the way it tastes. Services: the timely and courteous delivery of my salt as scheduled. I was also asked to comment on any telephone contact. I had forgotten that I called about the filter for my kitchen drinking water. I mentioned that the filters has not been changed in 4 years. A technician was dispatched the next day, and arrived early. He tested the water and determined which filters needed to be changed. (Thankfully not the more expensive ones!). Appreciated the timely response.
Great product, great price. I don’t ever want to be without one.
Culligan delivered our salt on time and even asked if they could fill our large salt tank. Very courteous and professional.

Great company to have your water Softner with. They come out to your home every month to add water solftner supplies to system and to check it. It only cost me $41 a month for the water softener system.
Great service! Thanks
I recently had Culligan of Seguin-New Braunfels replace my old water softener, and I couldn't be happier with the service I received! From the initial contact with the office staff to the final installation, the entire experience was excellent. The office team was incredibly friendly and kept me well-informed throughout the process with great communication. The installer who came to my home was not only very helpful in explaining the new system but also demonstrated impressive knowledge during the installation. They were efficient, professional, and a pleasure to work with. I highly recommend Culligan of Seguin-New Braunfels to anyone in the area looking for reliable and high-quality water treatment services. Their team is top-notch!
The Culligan Team has always been great to work with. Very helpful and courteous. Great Service by great people
I cannot say enough about my experience with Culligan of Seguin-New Braunfels. Specifically, starting from Jennifer who got me the details I needed, to scheduling Matt who came out and tested my water and determined what I needed to prepare for my installation - I loved the pricing options available and definitely appreciated the flexibility to be able to decide what's best for me. And it didn't stop there. I had the privilege to meet the awesome installation tech Hurley who was beyond accommodating to this "new to Texas" customer, who had zero clues about the effects of the TX water on my skin. He helped me fully understand my system, what it can do, and also if anything goes wonky on it. He took the time to also give me tips and tricks ensuring that I feel comfortable at all times with the system and know what to do in case of anything crazy like power outages, etc. Beyond his professionalism, he was super kind, genuine, and listened very well while being mindful to really understand my questions and provide solutions. Definitely would recommend to anyone who is looking for A+++ service. Super grateful that I now have softened water and clean drinking water to boot. An awesome Texas welcome, indeed!!! 🙂
Awesome service and value!

Usually, if your water smells like sulfur or rotten eggs, the reason is because your water has high Hydrogen Sulfide (H2S) content.

H2S is a gas that is released from the earth and finds its way into groundwater. It’s especially common in well water located near shale, sandstone, coal, peat, or oil.

(Occasionally, a rotten-egg smell in your water could also be caused by a water heater or by sewage pollution in your water. If you’re on city water, the most likely explanation is your water heater.)

A rotten-egg smell in your water may be strongest right after turning the water on, as heat forces the gas out of the water and into the air
H2S dissolves in water to create a weak acid that can corrode metal pipes

Negative Effects of H2S

In addition to potential health risks, having H2S in your water can cause all sorts of annoying problems. H2S in your water can:

  • Cause coffee and tea to be discolored and taste funny
  • Corrode metals (steel, copper, iron, brass), including silverware
  • Cause foods cooked with water to taste “off”
  • Create yellow or black stains in your bathroom and kitchen 

How Do You Fix It?

Here at Culligan, you can find everything you need to get rid of H2S and that sulfur/rotten-egg smell from your water.

The first step we have to take is to test your water, so we can be sure of the real cause of the rotten-egg smell.

Fortunately, here at Culligan we offer this service free. One of our water experts will come to your home to test the water (you can’t send it away to a laboratory because H2S is a gas and could dissipate during transport) and let you know the source of your rotten-egg smell. You’re under no obligation whatsoever. 

Culligan water treatment systems can completely remove the rotten-egg smell from your water
